Ruach

The Isle of Winds, visited by Pantagruel and his fleet on their
way to the Oracle of the Holy Bottle, is the isle of windy hopes and
unmeaning flattery. The people of this island live on nothing but wind,
eat nothing but wind, and drink nothing but wind. They have no other
houses but weathercocks, seeing everyone is obliged to shift his way of
life to the ever-changing caprice of court fashion; and they sow no
other seeds but the wind-flowers of promise and flattery. The common
people get only a fan-puff of food very occasionally, but the richer
sort banquet daily on huge mill-draughts of the same unsubstantial
stuff. (Rabelais: Pantagruel,
iv. 43.)
